“…There has been rapid progress in recent years on the research of antimicrobial behavior of MOFs, along with the antimicrobial application of MOFs and their composites [ 191 , 193 ]. The antimicrobial mechanism of MOFs is mainly accredited to the inherent biocidal nature from their metal ions and may also be from the antimicrobial organic ligands [ 191 , 193 – 195 ].…”

“…Ma et al [ 195 ] combined MOFs and cellulose fibre (CF) via simple in situ generation and established multifunctional MOFs@CF air filters. The ZIF-8@CF filter exhibited high filtration efficiency of 98.36% against 0.3 μ m particles, high gas adsorption ability, and excellent antibacterial activity against E. coli under a pressure drop of 134 Pa.…”

Face Masks in the New COVID-19 Normal: Materials, Testing, and Perspectives

The increasing prevalence of infectious diseases in recent decades has posed a serious threat to public health. Routes of transmission differ, but the respiratory droplet or airborne route has the greatest potential to disrupt social intercourse, while being amenable to prevention by the humble face mask. Different types of masks give different levels of protection to the user. The ongoing COVID-19 pandemic has even resulted in a global shortage of face masks and the raw materials that go into them, driving individuals to self-produce masks from household items. At the same time, research has been accelerated towards improving the quality and performance of face masks, e.g., by introducing properties such as antimicrobial activity and superhydrophobicity. This review will cover mask-wearing from the public health perspective, the technical details of commercial and home-made masks, and recent advances in mask engineering, disinfection, and materials and discuss the sustainability of mask-wearing and mask production into the future.

“…Naruporn et al [ 146 ] fabricated a honeycomb structure of the TiO 2 -decorated hydroxyapatite composite (HA/TiO 2 ), and this membrane showed 90–95% antibacterial efficacy against E. coli and S. aureus when exposed to UV light for 6 h. Recently, metal organic frameworks (MOFs) have been applied as a bactericidal agent, where ROS is generated from metal ions to kill bacteria [ 147 ]. ZIF-8, MOF-199, and Ag-MOF were tested by incorporating in the cellulose filters, and the incorporated filter showed ~99.9% bactericidal efficacy against E. coli [ 148 ].…”

With increasing air pollution and sporadic outbreaks of epidemics, there is ramping attention on the filtration devices. The main constituents of airborne pollutants are particulate matters of solid particles, liquid aerosol, bioaerosol/bio-droplets, and gas/vapor. With the growing demand for high-performance filters, novel materials and functionalities are being developed applying advanced technologies. In this paper, recent developments of fiber-based particulate filters are reviewed, with a focus on the important performance parameters and material properties. Trends in technology and research activities are briefly reviewed, and the evaluative measures of filtration performance are reported. Recent studies on the advanced filter materials are reviewed in the aspect of polymers and the fabrication process of fibrous assembly. The characterization method including 3D modeling and simulation is also briefly introduced. Multifunctional filters such as antimicrobial filter and gas and particulate filters are briefly introduced, and efforts for developing environmentally sustainable filters are noted.

“…19 Therefore, we speculate that the MOF on wood/bamboo does not release its metal cations; instead, the bacteria interact with the copper cations on the surface of the MOF, which has adverse impacts on the growth and reproduction of bacteria. 12,45…”
